Title: Inner ring for constant velocity universal coupling
Inventor: KOBAYASHI MASAZUMI
IPC: F16D3/20
Filed: 1994-07-29
Abstract: PURPOSE:To provide the inner ring of a constant velocity universal coupling which is constituted to suppress a protrusion formed during a high working angle high torque load operation and miniaturize the device and be suitable for high torque by smoothly interconnecting a chamfered part and an outer spherical surface through an arcuate surface. CONSTITUTION:In the inner ring of a uniform universal coupling formed in such a manner that a chamfered part 3 is located between an outer peripheral surface 1 and a ball groove 2, an edge part 4 on the ball groove side is left as before and instead of an edge part 5 on the outer peripheral side on the conventional side, this part forms an arcuate surface 8 and a portion between the chamfered part 3 and the outer peripheral surface 1 is smoothly continued through the arcuate surface 8. This constitution decreases thickness compared with that of the conventional edge part 5 on the outer peripheral side and reduces a protrusion amount in a radial direction by an amount equivalent to the decrease of thickness. Further, since the portion therebetween is smoothened through the arcuate surface 8, centralization of a stress is relaxed. Thus, even when high torque is applied at a high operating angle and an edge part 4 on the ball groove side is squeezed by a ball 6, the thickness of an arcuate surface 8 part is decreased to a value lower than that of a conventional type and centralization of a stress is relaxed, formation of a protrusion is suppressed.

Abstract: PURPOSE:To obtain a resin molded semiconductor device having small temperature drift by absorbing the resin stress change to a chip coating material by covering a mounted pellet with the chip coating material when the pellet is mounted at the pellet mounting unit of a lead frame with silver paste. CONSTITUTION:A paste 16 of semiconductor chip is mounted via silver paste on a tab 12 of the pellet mounting unit of a lead frame 10, and the electrode of the pellet 16 is electrically connected to the inner lead of the frame 10 via a wire 18.

Title: Reverse charge preventing system for distributed power supply
Inventor: KAWASAKI KENSUKE
IPC: H02J3/38
Filed: 1990-07-05
Abstract: PURPOSE:To reliably reverse charging of a distributed power supply by connecting a load for reverse power flow at a point closer to the power system side than a point where a reverse power flow detecting means is connected with a drop wire thereby generating reverse power flow upon opening of a circuit breaker. CONSTITUTION:Upon opening of a circuit breaker 15 in a power system 10, no power is fed from the power system 10 to a domestic load 23. In other words, reverse power flows through a reverse power flow monitoring point Z. When a reverse power flow detecting circuit 24 detects reverse power flow for a predetermined time or longer, an output control circuit 25 makes a judgment that the circuit breaker 15 is opened and interrupts output from am inverter 22. According to the arrangement, reverse charging from a distributed power supply 20 can be prevented.

Abstract: PURPOSE:To improve the transfer efficiency of signal charges, by arranging a transfer gate such that its end directed to the signal charge transfer direction is positioned identical with the ends of transfer electrodes directed to the signal charge transfer direction. CONSTITUTION:A transfer gate 26 is arranged such that the end thereof directed to the signal charge transfer direction is in conformity with the ends of transfer electrodes 23 and 24 directed to the signal charge transfer direction. The narrow channel effect is thereby decreased and a built-in well 34 is formed at a terminal end in the direction of signal charge transfer on a unit transfer basis (equivalent to a single transfer electrode). When a signal charge is transferred in this construction, a potential well produced under the next stage transfer electrode becomes deeper than the built-in well. The signal charges are thereby enabled to be transferred completely without any residual charge.
